Abstract: We formulate an extension of Maldacena's AdS/CFT conjectures to the case of branes located at singular points in the ambient transverse space. For singularities which occur at finite distance in the moduli space of M or F theory models with spacetimefilling branes, the conjectures identify the worldvolume theory on the pbranes with a compactification of M or IIB theory on AdSp+2 × HDp2. We show how the singularity determines the horizon H, and demonstrate the relationship between global symmetries on the worldvolume and gauge symmetries in the AdS model. As a first application, we study some singularities relevant to the D3branes required in fourdimensional Ftheory. For these we are able to explicitly derive the lowenergy field theory on the worldvolume and compare its properties to predictions from the dual AdS model. In particular, we examine the baryon spectra of the models and the fate of the Abelian factors in the gauge group.
